WebHuman spaceflight without change to International Space Law will remain very much the same. The Outer Space Treaty, the Liability Convention and Rescue Agreement remain an essential element to all space activities. Luckily, the application of these treaties was considered to allow some form of the evolutionary process in their interpretation. WebContinuity in Metric Spaces Remember, given f : X !Y and A ˆY the inverse image is a subset of X de–ned as: f 1(A) = fx 2X : f(x) 2AgˆX The inverse image is used to provide a characterization of continuous functions. Theorem Let (X;d) and (Y;ˆ) be metric spaces, and f : X !Y. Then f is continuous 1
